A flexible LED packaging structure includes two or more metal foil substrates. One or more LED chips are assembled onto the primary metal foil substrate by silver glue or solder paste or eutectic. A secondary metal foil substrate is electrically connected with the LED chip by wires or eutectic. There is a spacing between the primary and secondary metal foil substrates. A packaging colloid, made of a flexible material, is fully covered onto the LED chip and partially covered onto the primary and secondary metal foil substrates, such that the lower surface of the primary and secondary metal foil substrates is exposed. With this principle, a plurality of LEDs is electrically connected in parallel or in series, and the metal foil substrate could be used to improve the heat-radiating effect, thus enabling flexible assembly onto multiple lightings.
